To all whom it'may concern;-

Be it .known that I, THOMAS l. herren, a citizen of the United-States, residing at Oak- California, have invented new and useful linprovements in Chaiige-ltlaking1 Machines, of

cation'.

T his Kinvention relates`to a change niaking machine, the object of the invention being to provide a machine of this character which shall be simple and economical in construction, accurate 1n use, Which will have a large range of' operatiqn, and will be not liableto Aget out of order.

' In the accompanying'dratving, Figure 1 a -front view cf the machine; Fig. 2 is a -brokenlan viewlthereoi, the too plate heing d) iO; 3 is a ver` remove to showsT the interior; j tical transverse section; Fig. :fr is a broken longitudinal section, looking from the rear;

Fig. 5 .is a view of one of the selector.plates,

detached.

Referrinfy tofthe draWin s 1 indicates the 'frame of the maehineupon which is secureda'base plate 2, having thereon dividing Walls 3, forming discharge channels for the coins.

VOver said base plate is a row of cylindrical coin'receptacles 5 -each of suitable diameter for receivin the proper coin. These recep'- tacles'are a secured y solder in groups, and one oup is secured yto the next by upper and oWer blocks 6, 7 soldered thereto, and the Whole roW of receptacles secured to the base plate by nieans of screws S screwed through said baseplate intolower blocks 7. Secured `upon the .iront sides of the receptacle is an indicator plate 9. Extending upwards on said frame behind said vhase plate are posts 10 connected at the to by a bar l1 andl vthrough'bearings 12 on sai bar 11 are fershafts extending through thevupper blocks 6 and also through the indicator plate 9, and carrying -on their fr nt ends crank handles 15, upon tlie'rear si es of which are secured` pointers 16 of spring iiietal the ends of which, when said shafts are rocked, pass in front of index lnumerals 17 indicating the amount oi change which is to be made.

Corresponding to each series of index numerals is a circular' series oi sockets A18a-nd each pointer carries asmall rearwardly extending Apin or knob 1 9, which, gwhen'the pointer aocuratelyfpoints to the indexnumeral V'corresponding 'to the desired change, drops lhy the spring pressure of ,the :pointer l Specieaton'of Letters Patent. c reputation sied. .epfl ni, ieu?. .serie no, 365,135.

into a corresponding socket 18, and holds the handle in position. It also serves to apprise tneeoperator when the handle has been turned to the proper position.

Upontherear end of each rocking'shat-is a crank 21 the outer end dfwhich is connected hy. a link -22lto"a .vertically sliding selector .plate 23, which carries at its ends. `guides 24, hyfrneans oiwhich the late slides upon posts 10. By this means t e selector/ p ate' 23 can be raised or lowered'toan desired position, the operative positions o said plate corres dnding with the positions ofthe crank hand e 1n which the vknob 19 drops into one of the sockets.

" Mounted in hearings 25 on the fratrie is a rock shaft 27 carrying at its end a crank hana pair of crank` dle. 28, and also vcarryin arms 30 connectedv by lin-ks 31 with an ejector frame 32, said frame sliding upon horizontal guide rods `33. Said :ejector frame'carries a series of cylinders 3'4, one for each of the coin receptacles, each cylinder beingclosed at itsfro'nt end except iler a small aperture through whichA passes aneedle like i ejector 35, attached at vits rear end to a piston or disk 36 sliding in sa'id cylinder, between which disk andthe other end of thelcylinder is interposed acoiledspring?. The front ends of said ejectors pass ,through guiding aperturesl 38 iorni'ed in the frame, and each selector platev is formedv With groups oi' apertures 40, the apertures of any group being so :arranged as to permit certain of the ejectors --to pass therethrough, while other ejectors upon the continued forward movement ofthe ejector frame passes through a guideway 42,- and then through a'hole atthe becket" the'coinY receptacle 5 pposite said Uuideway.

.The Ybottonil of the'rec'eptacle 5 is Ioiiried at itsv front side with aslot 43 sufiiciently large to permit the coin to pass therethrough and the continued movement 0fsaid ejector .in said receptacle, therefore 4yiously deposited in 'said receptacle.' But if .it should be desired to give a larger quantity of change, as for instance, three cents, then the crank handle is 'turned to the proper position, as indicated by the pointer and this causes the selector plate to descend until a row of three apertures are respectively in alinement with three of the ejectors, so that the forward movement of the ejector frame in like manner as before ejects a cent from each of three of said receptacles. Arranged in a row with the four receptacles for cent coins is a receptaclefor 5 -eent coins, arid upon turning the crank handle to the index 5, there is presented -to the group of e'ectors a single aperture only through W ich an ejector can pass, it then passing into the bottom of the 5-cent receptacle, ejecting therefrom such a coin. And in like manner for an amount of change greater than -cents a row of apertures would be'plac'ed in line with the ejectors by which a -cent coin would be ejected, together with one or-more of the l-cent coins. Precisely the same mode of operation applies to coins of higher denomination, the receptacles being divided into groups, the first group giving change from .parting from the spirit thereof.

one cent u to ten, the second fromten cents up to a do lar, and the third group from one dollar to ten dollars, and the same arrangement can be extended indefinitely. I have herein, for simplicity and clearness, shown only two such groups.

It is to be understood that the precise details of the construction of this invention may be varied in many Ways without de- For instance, the'ejectors, instead of being selectively arrested by the selector plate can be selectively operated thereby, in this case the a ertures being used to receive those needles w ich are not to be used in ejecting coins, while those needles which are engaged by the selector plate at points where there are no apertures are proj ected thereby and eject the coins. In this case the selector plate would be placed behind the 'needles instead of in front.

The form of the selector plates may also be varied; thus they may be made of a rotar disk form instead of vertically slidable. Such changes, however, 'are considered to come within the scope' of my invention.

5() indicates a chute the mouth of which is closed at the front by a vertically sliding gate 52, said gate being maintained in its closed position by gravity. The upper portion of said gate is closed to prevent the escapeof' the coin, but the gate extendsjbelow said mouth, and its lower portion is open, 'as

shown at 33. Upon raising the gate by the bination of a series of coin-receptacles, a corresponding series of reciprocable ejectors, guides for said ej ectors, means for each ejector arranged to normally hold the same in operative position, a selector-plate, traversing the path thereof, and provided with relatively arranged apertures, means to position said ejectorplate so as to selectively permit r certain of the ejectors to pass through the apertures of said plate, and means to advance the selected ejectors as a unit.
